Th s invention relates to blade attachments o plows and more particularly to a ditching blade attachm n for a two ottom, tract r operated o It is am he bj cts of the invent on t proe a ditchi g blade atta hment tor a tract operated plow which blade attachment, when mounted on a plow, converts the plow into a ditching implement which can also be. used. as a snow plow andfor other purposes, which attachment can be quickly and easily applied to an existing plow with no material modification of the plow construction, and, which is simple and di lable in construction, economical to manufacture, and positive and efiective in use,

Other objects and advantages will become apparent from a consideration of" the following description and the appended claims in conjunction with the accompanying drawings. wherein:

Figure 1 is a top plan View of a tractor and a tractor connected plow with a ditching blade illustrative of the invention operatively mounted on the plow:

With continued reference to the'drawings, the tractor illustrated inFiguresl and 2 is an: existing form of farm tractor of the type known to the trade as a Ford-Ferguson Ford or Ferguson tractor and has a rear axle l supported by rear wheels I'! journalled at respectively opposite ends or the rear axle, a differential mechanism [2 at the mid-length location of the rear axle, a transmission mechanism l3 connected to the'differential mechanism and constituting a part of the tractor frame, a pair of tension links. M and I pivotally connected at their front ends to the rear axle It at respectively opposite sidesof the differential mechanism l2 and extending rearwardly tr m the re r axl a lift shaft- "5 carried by th ra t r ab ve d. ome ha -ahe d of the din rential mechanism struts H and t8 connected between the respectively opposite ends of: the lift shaft t5 and the tension links; 14 and I5 intermediate the length of the latter, and a compression l nk is connected at its. front end to a rocker arm 20 which controls the automatic operation of the tract r implement liitine. v manuall operated lever 21 is connected to this valve to change the setting of. the valve sothat theimplement can be completely. raised and lowered und r ma ual control.

A triangular structure. 22 is connected. atits apex to the rear endof thecompression link 19 a s pivotally nnected at there p ctivelv opposite ends of its base to the rear ends of'the tension links [4 and Hi.

The plow comprises twoplew beams- 23 and 24 rigidly'seoured intermediatetheir length to the structure 22 and disposed? inspaoed apart and substantially parallel relationshipto each other. These plow beams: are held substantially perpendicular to the base of the structure 221 by diagonal braces 25 'andLZ'G and" are held in substantially parallel relationshipto each other by adiagonal brace 21. connectedat. its opposite ends to. the beams 23 andzzllrrespectively.

The beam 23iscurveddownward1y at-itsrearward ends to provide a plow stem 33am, a p w bottom including the. usual mold board 28- is mounted on this stem! The beam. 2.4- is curved downwardly to provide a plow stem tllland a plow bottom, including the mold board'ZSl mounted on this stem;

The blade 301 is a steel plate of elongated. rectangular shape having athickness of approximately inch and transversely curved to a partly cylindrical shape.

This plate is securedtothe plow with its lower edge at slightly above the plow points 28. and 29, as illustrated in Figure. 2, and so that its upper edge extends substantially. to. the top ofv the plow beams 23' and 24 at the upper ends or the plow stems 3'3. and 3.4 The. plate is provided in its upper edge with two rectangular notches 3.5 and 36 which receive the plow beams 23 and 24 respectively and the length of the plate and the location of these notches is such that when the plow beams are. received. in the notches one end of the plate extends slightly beyond the front edge of -the moldboard 28 oi the. leadin v plow and the. other end of theplate extends. away fromthe front edge of the. mold board 23 of the other plow a distance substantially equal. to the distance between thev two. plows" The upper corner of. the. plate at the end'there. of remote. from the plows curved forwardly, as. indicatedat .31 to. give, this end of, thev blade a somewhat spoon or mold board shape for turning earth at this end of the blade inwardly.

Bracket structures 38 andv .39. are. provided adjacent the

notches

35 and 36 respectively and each of these brackets as particularly illustrated in Figure 3, comprises two flat L-shaped members 40 and 4| disposed at respectively opposite sides of the corresponding notch with their stems substantially perpendicular to the top edge of the plate and their upper end portions disposed substantially at right angles to their stem portions and extending away from the convex side of the plate. A short bar 42 is connected at its opposite ends to the outwardly extending portions of the members 40 and 4t.

Clamps 43 and 44 are secured to the plow beams 23 and 24 respectively a short distance ahead of the upper edge of the blade. Each of these clamps, as is also particularly illustrated in Fig. 3, includes a member 45 of rectangular form which receives the plow beam and an upstanding stem or bar 46 secured to the member 45.

The blade is secured to the plow beams by short chains 41 and 48 of which the chain 41 extends around the bracket 38 under the corresponding bar 42 and the outwardly extending upper end portions of the bracket members 40 and 4| and around the stem 46 of the associated clamp 43. This chain is provided at one end with a hook 49 so that the chain can be tightly engaged around the corresponding bracket and clamp stem. The chain 48 is similarly engaged around the bracket 39 and the stem of the clamp 44.

When the plow beams are received in the notches 35 and 3B of the blade the blade will remain in operative position on the plow as long as the plow is lowered and the plow bottoms and the blades are in operative position. However, when the plow is raised by the implement lift mechanism of the tractor, the blade would fall ofi of the plow if it were not held securely in place by the chains 47 and 48.

With this arrangement the point of the forward plow acts as a cutting or digging implement which cuts the adjacent lower corner of the blade into the ground. With the plow bottoms disposed one ahead of the other, the blade is inclined relative to the draft line of the plow outwardly and rearwardly from the leading plow bottom and when its lower corner adjacent the leading plow bottom is cut into the ground it moves the displaced earth rearwardly and tward its end remote from the leading plow bottom.

The implement control mechanism of the tractor holds the blade and plow bottoms at the proper operating depth, and the mold board of the leading plow bottom resists the end thrust of the blade and provides a rounded edge at the corresponding edge of the ditch. The downward pressure of the implement control mechanism causes the blade to incline upwardly away from the leading plow, providing an inclined slope at the opposite side of the ditch.

The plow and blade combination may also be used as a. terracing plow or as a snow plow and for other purposes which will be apparent to those skilled in the art.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

What I claim is:

l. A ditching implement comprising a two bottom plow having spaced apart and substantially parallel beams each formed at one end to provide a curved plow stem one of which is disposed rearwardly of the other, and plow bottoms secured one on each stem and each having a substantially vertically disposed and concavely curved front edge, a blade of elongated rectangular shape transversely curved so that its convex side fits the curved front edges of said plow bottoms and disposed against the front edges of said plow bottoms and extending outwardly beyond the rearwardly disposed plow bottom, said blade having spaced apart notches in the upper edge thereof respectively receiving said plow beams, and means secured to said blade adiacent said notches and engaging said beams to secure said blade to said plow.
